Still rare in some areas, but populations have markedly recovered following earlier pollution problems in central and western Europe.

|Habitat and Ecology:||Habitat: |
Adults live in coastal waters and estuaries and spawn in strong-current habitats of rivers and streams. Ammocoetes burrow in detritus-rich sands or clay sediments.
Predatory, with anadromous and landlocked populations. Adults migrate into rivers from autumn to spring. Migration is mainly nocturnal and ceases at low temperatures. Spawning season starts when water temperature rises above 9°C, which depends on latitude, starting in late March in France and mid-June in Finland. Spawning individuals cease their normal daylight avoidance reaction and reproduce on sunny days. Males dig shallow nests in habitats with fast current. Spawners form large aggregations. Adults die after spawning. Ammocoetes stage lasts 2½-3½ years. Ammocoetes feed on detritus and micro-organisms. After metamorphosis (from late summer to late autumn), most juveniles overwinter in freshwater and migrate to the sea in spring. At sea, adults prey on a wide variety of fish species, mostly Clupeidae and Gadidae. Feeds on body tissues of prey, which is usually killed while its flesh is excavated. Adults feed for 2 (rarely 1) summers before migrating to the spawning grounds. Individuals feeding for only a single summer before breeding are smaller. Landlocked population of Loch Lomond feeds for only one summer, then stops feeding and migrates in autumn to spawning grounds in River Endrick.
|Movement patterns:||Full Migrant|
|Use and Trade:||This species is harvested for human consumption.|
|Major Threat(s):||No major threats known.|
|Conservation Actions:||No information available.|
|Errata reason:||When the 2010 assessment of this species was published in 2011, a 2013 citation reference was accidentally attached to the account and hence the previous version of the assessment showed it as being published in 2013 when it should have been 2011. The error is corrected here and is therefore given a 2016 citation date; the 2011 reference that should have been used in the citation is under the References.|
